Hi - wonder if anyone can help?
My Belling Dishwasher (IDW604 prod # 444445898, ser # 60302116) washing peformance is poor. It's about a year old and leaves dishes dirty, especially top shelf. It used to be good, but recently has started to leave dishes dirty (scummy residue on everything). It's never been as good as my prev m/c - an ancient Indesit (but the wife wanted this built in unit...)
I've cleaned everything I can see, run dishwasher cleaner, checked the arms (and ball valve is free and clean in top arm). The waste has a long run, but does go straight up to worktop height before gradually coming down.
Are there any additional filters hidden that may be blocked?
any advice greatly appreciated.
